    • Multilevel coding of broadcast video over wirless channels 

      Cakareski, Zeljko; Ahmed, Nasir; Dhar, Aditya; Aazhang, Behnaam (2002-05-20)
      This paper addresses the problem of broadcasting video over wireless channels. In such a scenario, different end users perceive the video signal through channels with different quality. We propose a source-channel coding ...
    • Multilingual Open-Content Signal Processing Laboratories in Connexions 

      Frantz, Patrick; Baraniuk, Richard G.; Choi, Hyeokho; Jones, Douglas L. (2004-11-01)
      Due to inherent factors like a small and fragmented market and rapid hardware obsolescence, the conventional textbook is inadequate for DSP laboratory education. Freely available open-content materials that enable and ...
    • Multimodal snapshot spectral imaging for oral cancer diagnostics: a pilot study 

      Bedard, Noah; Schwarz, Richard A.; Hu, Aaron; Bhattar, Vijayashree; Howe, Jana; Williams, Michelle D.; Gillenwater, Ann M.; Richards-Kortum, Rebecca; Tkaczyk, Tomasz S. (2013)
      Optical imaging and spectroscopy have emerged as effective tools for detecting malignant changes associated with oral cancer. While clinical studies have demonstrated high sensitivity and specificity for detection, current ...
    • Multiphysics model of a cardiac myocyte: A voltage-clamp study 

      Krishna, Abhilash (2013-07-24)
      We develop a composite multiphysics model of excitation-contraction coupling for a rat ventricular myocyte under voltage clamp (VC) conditions to: (1) probe mechanisms underlying the response to Ca2+-perturbation; (2) ...

      Krishna, Abhilash; Valderrábano, Miguel; Palade, Philip T; Clark, John W Jr (0001-10-30)
      Background: The objective of this study is to develop a comprehensive model of the electromechanical behavior of the rat ventricular myocyte to investigate the various factors influencing its contractile response. Methods: ...
    • Multiple access schemes over multipath fading channels 

      Erkip, Elza; Aazhang, Behnaam (1998-10-20)
      We compare the performance of different accessing schemes for communication over an additive white Gaussian noise multiple access channel with multipath fading. We assume that only the receiver can track the channel ...
    • Multiple Basis Wavelet Denoising using Besov Projections 

      Choi, Hyeokho; Baraniuk, Richard G. (1999-10-01)
      Wavelet-based image denoising algorithm depends upon the energy compaction property of wavelet transforms. However, for many real-world images, we cannot expect good energy compaction in a single wavelet domain, because ...
    • Multiple scattering of broadband terahertz pulses 

      Pearce, Jeremiah Glen (2005)
      Propagation of single-cycle terahertz (THz) pulses through a random medium leads to dramatic amplitude and phase variations of the electric field because of multiple scattering. We present the first set of experiments that ...
    • Multiple wavelet basis image denoising using Besov ball projections 

      Choi, Hyeokho; Baraniuk, Richard G. (2004-09-01)
      We propose a new image denoising algorithm that exploits an image's representation in multiple wavelet domains. Besov balls are convex sets of images whose Besov norms are bounded from above by their radii. Projecting an ...
    • Multiple Window Time Frequency Analysis 

      Bayram, Metin; Baraniuk, Richard G. (1996-06-01)
      We propose a robust method for estimating the time-varying spectrum of a non-stationary random process. Our approach extends Thomson's powerful multiple window spectrum estimation scheme to the time-frequency and time-scale ...
    • Multiple Window Time Varying Spectrum Estimation 

      Baraniuk, Richard G.; Bayram, Metin (2000-01-20)
      We overview a new non-parametric method for estimating the time-varying spectrum of a non-stationary random process. Our method extends Thomson's powerful multiple window spectrum estimation scheme to the time-frequency ...
    • Multiple window time-frequency analysis 

      Bayram, Metin (1996)
      The bias-variance trade-off is an important issue is spectrum estimation. In 1982, Thomson introduced a powerful multiple window method for stationary signals that deals with the bias-variance trade-off in an optimal ...
    • A Multiplexable, Microfluidic Platform for the Rapid Quantitation of a Biomarker Panel for Early Ovarian Cancer Detection at the Point-of-Care 

      Shadfan, Basil H.; Simmons, Archana R.; Simmons, Glennon W.; Ho, Andy; Wong, Jorge; Lu, Karen H.; Bast, Robert C. Jr.; McDevitt, John T. (2015)
      Point-of-care (POC) diagnostic platforms have the potential to enable low-cost, large-scale screening. As no single biomarker is shed by all ovarian cancers, multiplexed biomarker panels promise improved sensitivity and ...
